CONNECTION-GUARD FOR EYEGLASSES.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed January 18, 1909. Serial No. 472,855.

To all whom it may concern:

Be it known that I, MAURICE B. KORMAN, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented new and useful Improvements in Connection-Guards for Eyeglasses, of which the following is a specification.

This invention relates to new and useful improvements in connection guards for eyeglasses, and it has primarily for its object to provide a novel device of this character wherein the connection screw is held against accidental displacement and from contacting with the nose of the wearer of the eyeglasses to obviate the screw injuring the flesh.

It is also an object of the invention to provide a novel device of this character wherein a plate is employed in conjunction with the box to hold the screw against accidental displacement, said plate contacting with the nose of the wearer, said plate and box having co-acting means to hold the plate normally in position.

Furthermore, the invention has for an object to provide a novel device of this char acter which will be simple in construction, efiicient and advantageous in practice and comparatively inexpensive to manufacture.

lVith the above and other objects in view, the invention consists of the details of construction and in the novel arrangement and combination of parts to behereinafter more particularly referred to.

In describing the invention in detail reference will be had to the accompanying drawings forming part of this specification wherein like characters of reference denote corresponding parts in the several views and in which,

Figure 1, is a view in perspective of a fragment of an eyeglass illustrating the invention; Fig. 2, is a fragmentary view in section longitudinally of the plate; Fig. 3, is-a view in top plan illustrating the invention, the bridge piece being in section and the lens-post being omitted; Fig. 4, is a central cross section through the box; and Fig. 5, is a view in perspective, detached, of a modified form of guard plate.

In the drawings 1, denotes a lens-post of any ordinary or preferred structure terminating in the box 2, said box 2, having its free face open but provided with the in turned lips or flanges 3.

Within the box 2, projects an end of the bridge piece 4, and'the shank 5, of the nose piece 6, said shank -5, and bridge piece 4:, being secured to the lens-post 1, by the screw 7, as in general practice. WVhen thus assembled there is sufficient space between the top of the screw 7 and the under faces of of the connection guard plate 8, which, as is thought to be apparent to those skilled in the art to which this invention pertains, effectually holds the screw 7, against accidental displacement and serves as a shield to protect the nose of the wearer from contacting with the head of the screw 7. The plate 8, is L-shaped in form and when in applied position foot 9, thereof, or more particularly the free end portion thereof abuts the upper edge of the shank 5, of the nose piece 6. This is done to limit the down movement of the plate 8, within the box 2.

To assure positive retention of the plate 8, within the box, said plate is provided adjacent its longitudinal edges and at a point approximately centrally thereof with the pockets or recesses 10, into which points 11, projecting inwardly from the flanges 3, are adapted to extend. This arrangement positively holds the plate in position under normal conditions yet readily permits its removal by slight pressure thereon. While the points 11, may be formed in any desired manner it is preferred that they be pressed out as is fully disclosed by the drawing.

In Fig. 5, a connection guard plate is shown which is similar in every respect to the One hereinbefore described with the exception that the stem or main portion 12, thereof is provided with the central longitudinal raised portion 13. This raised portion is adapted to fit snugly between the opposed edges of the flanges 3, and thus provides an unobstructed surface for contact with the nose of the wearer.

I claim:

In combination with the box of a lens post of eyeglasses having inturned flanges, a bridge piece extending within said box, a shank of a nose piece extending within the box in advance of the bridge piece, and a connecting screw passing through the shank the flanges 3, to permit the insertion therein and bridge piece; an L-shaped guard plate ing points DIGSSGdlhGIQfYOHl to extend with- 10 fitted within said box between the shank and in the pockets of the stem of the plate.
